These small but essential components are crucial for creating strong and reliable connections in woodworking, metalworking, and other DIY projects. In this buying guide, I will share my experience and knowledge to help you make an informed decision when purchasing 1 4 20 threaded inserts.

What are 1 4 20 Threaded Inserts?

Before diving into the buying guide, it is essential to understand what exactly are 1 4 20 threaded inserts. These are small metal fittings with internal threads that are designed to be inserted into a pre-drilled hole in a material. The “1/4” refers to the size of the bolt that fits into the insert, while “20” indicates the number of threads per inch.

Material

The first and most crucial factor to consider when purchasing any type of threaded insert is the material it is made of. The most commonly used materials for threaded inserts are brass, stainless steel, and zinc-plated steel. Each material has its own set of advantages and disadvantages.

– Brass: Brass threaded inserts are known for their corrosion resistance and high strength. They also have good electrical conductivity, making them ideal for electronic applications.

– Stainless Steel: If you need extra durability and strength in your project, stainless steel threaded inserts are a great choice. They can withstand high temperatures and have excellent resistance to corrosion.

– Zinc-Plated Steel: These inserts offer high tensile strength at an affordable price. They also have good corrosion resistance thanks to their zinc coating.

Type of Installation

Another crucial aspect to consider is the type of installation method you need for your project. There are three types of installations available for threaded inserts:

– Press-In: Press-in or knock-in inserts require a press or hammer to be installed into a pre-drilled hole.
– Heat Insertion: Heat insertion involves heating up the insert before screwing it into place using a pre-heated tool or soldering iron.
– Self-Tapping: Self-tapping threaded inserts have sharp cutting edges that allow them to be screwed directly into a pre-drilled hole without any additional tools.

Size

The size of the insert plays a significant role in its performance and compatibility with your project. The most common size for 1/4-inch bolts is #10 thread size with an external diameter of around 0.375 inches. However, make sure to check the specific measurement requirements for your project before purchasing.

Quantity Needed

Lastly, consider how many threaded inserts you will need for your project before making a purchase. It is always better to buy more than what you think you will need as extras can come in handy in case any get damaged or lost during installation.

Final Thoughts

Purchasing the right type of threaded insert is crucial for ensuring strong and long-lasting connections in your projects. By considering factors like material, installation method, size, and quantity needed, you can make an informed decision when buying 1/4-20 threaded inserts. With this buying guide as your reference point, I am confident that you will be able to choose the perfect ones for all your future projects!
